Retraction Note to: Synthesis and characterization of a novel locally high dense sulfonated poly (aryl ether ketone sulfone) for DMFCs applications

Abstract

The authors have retracted this article [1] because Scheme 1, Scheme 2, Figs. 2, 3, 4, and 8, as well as significant parts of the text were duplicated from a previously published article by Yuan and Wang [2]. Both authors agree with this retraction.
